Reliability of the postpartum depression screening scale in the neonatal intensive care unit.

BACKGROUND: Rates of postpartum depression have been found to be significantly higher in mothers of infants in the neonatal intensive care unit (NICU) than the general population estimate of 10%-15%, making routine screening for these mothers essential. OBJECTIVES: The aim of this study was to examine the reliability (internal consistency) and construct validity of the Postpartum Depression Screening Scale with a sample of mothers of infants in the NICU. METHODS: A total of 111 (40% of eligible) mothers participated in the study. Mothers completed a brief demographic questionnaire and the screening scale at 14 or greater days postpartum. Estimates of internal consistency were evaluated using Cronbach's coefficient alpha. RESULTS: On the basis of the scale total score, 52% of mothers had a positive screen and an additional 30% received a score indicating that they were at-risk. Reliability estimates were consistent with previous research and indicate excellent internal consistency for the total score and adequate to good internal reliability for subscales scores. The coefficient alpha for total score equaled .95, and alpha for subscale scores ranged from .72 (Anxiety/Insecurity) to .89 (Suicidal Thoughts). Interscale correlations were consistently lower than subscale reliability estimates (coefficient alpha) and were lower than subscale-to-total score correlations, suggesting initial support for the proposed structure of the scale for mothers in the NICU. DISCUSSION: Most of this sample of mothers experienced significant symptoms of postpartum depression. The Postpartum Depression Screening Scale is a promising tool for screening mothers with infants in the NICU. Additional research is necessary to better understand the construct and predictive validity of scores among these mothers. Current and future research will contribute to the routine use of scale as a screening tool in this environment.

Locus of control and self-efficacy: potential mediators of stress, illness, and utilization of health services in college students.

Although many studies examine the biological phenomena that mediate the relationship between stress and illness, more research is needed regarding psychological variables that may mediate this relationship. Thus, the current study investigates the mediating effects of locus of control and self-efficacy in the relationships among stress, illness, and the utilization of health services in a sample of 159 college students. Results suggest that participants who endorse higher levels of stress also endorse higher levels of illness, higher levels of external locus of control, and lower levels of self-efficacy. In addition, structural equation modeling suggests that there are direct relationships between stress and illness and between illness and the utilization of health services. Further, locus of control appears to be a partial mediator in the relationship between stress and illness. Given the link established between stress and illness and the individual differences associated with reactions to stressful situations, it is important for future examinations to continue to identify potential mediators of the stress-illness link.

The relationship between maternal and paternal psychological symptoms and ratings of adolescent functioning.

Families with an adolescent between the ages of 11 and 18 years participated in a study examining the relationship between parental depressive and anxiety symptomatology and parental ratings of adolescents' functioning. This study indicated that mothers, fathers, and adolescents exhibited significant cross-informant correspondence (i.e. correlations) and very few significant differences in ratings of adolescents' functioning. After controlling for demographic variables and the ratings of other informants, mothers' depressive symptomatology was a significant predictor of mothers' ratings of adolescents' internalizing and externalizing behavior problems and competence. With regard to fathers' ratings, fathers' depressive symptomatology was a significant predictor of adolescents' internalizing behavior problems and competence, whereas fathers' depressive and anxious symptomatology was a significant predictor of adolescents' externalizing behavior problems. The findings of this study suggested the importance of considering maternal and paternal depressive symptomatology when parents are asked to provide ratings of their adolescents' functioning.
